Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies N18/670 with a precision bore diameter (d) of 670 mm, an outside diameter (D) of 820 mm, and a nominal ring width (B) of 69 mm. This configuration yields an effective cross-sectional wall thickness of 75.0 mm and an envelope ratio (D/d) of 1.22, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing N18/670 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 670 mm bore. For the 820 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for N18/670, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Built for demanding industrial environments, the N18/670 Single Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
